However, pregnancy was especially hard for the Avatar actress who's struggled with body issues after giving birth.

On Friday, the Guardians Of The Galaxy star went on Facebook and was EXTREMELY open to mothers everywhere about the physical changes she experienced.

She confessed:

"Your body changes dramatically, inside and out. You grow in places you never knew you could, and you are tired beyond belief. In some cases more than others, your body experiences a kind of trauma through childbirth that is difficult to explain unless you've had that experience. My case was like that, everything from my thyroid to my platelets crashed."
